Medicare Advantage Plan Subrogation vs Traditional Medicare: Attorney Implications

James Wong — Founder & Pharmacist, LienScripts | March 29, 2026 | 7 min read

Medicare Advantage plans have broader subrogation rights than traditional Medicare and pursue recovery more aggressively through private plan language. This guide explains how MA plan subrogation differs, the interaction with pharmacy liens, and strategies for PI attorneys navigating MA plan recovery demands.

Medicare Advantage (MA) plans possess subrogation and recovery rights that differ significantly from traditional Medicare's conditional payment framework, often making MA plan recovery demands more aggressive and harder to negotiate. MA plans are private insurers operating under Medicare Part C contracts, and they enforce subrogation through private plan language rather than the Medicare Secondary Payer Act's administrative process, giving them litigation options that traditional Medicare lacks.

• MA plans are private insurers with contractual subrogation rights enforced through plan language, not the CMS conditional payment process
• MA plan recovery demands are typically more aggressive and arrive faster than traditional Medicare conditional payment letters
• The MSP Act's private cause of action allows MA plans to sue directly for double damages, creating leverage traditional Medicare does not use
• Pharmacy liens remove medication costs from MA plan subrogation claims because the plan never paid for lien-dispensed prescriptions
• LienScripts generates a POGOS (Pharmacy-Organized General Occurrence Summary) report for every case, providing pharmacist-signed documentation that distinguishes lien-dispensed medications from plan-paid costs

How Medicare Advantage Differs from Traditional Medicare

Traditional Medicare (Parts A and B) is administered directly by CMS. When Medicare makes conditional payments in a PI case, recovery is handled through the Benefits Coordination and Recovery Center (BCRC) using an administrative process with specific notice requirements, dispute procedures, and pro-rata procurement cost reductions.

Medicare Advantage plans (Part C) are private health insurance plans approved by Medicare. Beneficiaries enroll in an MA plan instead of traditional Medicare, and the MA plan receives a capitated payment from CMS to provide all Medicare-covered services. The MA plan assumes the insurance risk and manages care through its own provider network.

For PI attorneys, the critical distinction is this: when an MA plan pays for injury-related treatment, the plan's recovery rights are governed by both the MSP Act and the plan's own contractual subrogation provisions. This dual framework gives MA plans tools that traditional Medicare does not have.

[!KEY] Traditional Medicare recovery is purely administrative — handled through the BCRC with structured timelines and dispute procedures. MA plan recovery combines the MSP Act's statutory framework with private contractual subrogation, giving MA plans the ability to litigate, demand double damages, and pursue recovery more aggressively than CMS ever does for traditional Medicare.

The MSP Private Cause of Action

The Medicare Secondary Payer Act, 42 U.S.C. section 1395y(b)(3)(A), creates a private cause of action that allows any entity that has made a conditional payment to bring a civil action for double damages against any entity responsible for making the primary payment.

Traditional Medicare rarely uses this provision directly. CMS pursues recovery through administrative channels — the BCRC demand letter, the appeals process, and ultimately Treasury offset if payment is not made.

MA plans, however, routinely invoke the private cause of action. MA plans are "entities that have made conditional payments" under the MSP Act, and courts have upheld their standing to sue. This means an MA plan can file a lawsuit against the PI plaintiff, the plaintiff's attorney, or the tortfeasor's insurer seeking double the amount of its conditional payments.

According to James Wong, PharmD, founder of LienScripts, "Attorneys who are accustomed to the traditional Medicare BCRC process are sometimes caught off guard by MA plan recovery demands. The MA plan's ability to threaten litigation and double damages changes the negotiation dynamics entirely."

[!TIP] When you receive a recovery demand from an MA plan, treat it with the same urgency as an active litigation demand, not as a routine administrative letter. MA plans have in-house recovery units or contract with specialized subrogation firms that will file lawsuits to enforce their rights.

MA Plan Subrogation Language

Beyond the MSP Act, MA plans enforce recovery through their plan documents. The Evidence of Coverage (EOC) — the MA plan equivalent of an SPD — typically contains subrogation and reimbursement provisions that mirror aggressive ERISA plan language.

Common MA plan provisions include:

First-dollar recovery. Many MA plans assert a right to full reimbursement from any third-party recovery, without reduction for attorney fees or the made-whole doctrine. This mirrors the most aggressive self-funded ERISA plan language.

Constructive trust provisions. Some MA plans claim that settlement proceeds are held in constructive trust for the plan's benefit until the subrogation amount is repaid. This creates a fiduciary obligation on the beneficiary and the attorney.

Assignment of rights. The EOC may require the beneficiary to assign their third-party recovery rights to the plan, giving the plan independent standing to pursue the tortfeasor directly.

Anti-made-whole language. MA plans routinely include provisions stating that the plan's recovery right exists regardless of whether the beneficiary has been fully compensated for all damages.

[!KEY] MA plan subrogation provisions combine the statutory power of the MSP Act with aggressive private contract language. Attorneys must obtain the EOC at intake and analyze the plan's specific subrogation provisions, just as they would analyze an ERISA self-funded plan's SPD. The EOC is the controlling document for the plan's contractual recovery rights.

Pharmacy Liens and MA Plan Subrogation

A pharmacy lien provides the same structural protection against MA plan subrogation as it does against traditional Medicare and ERISA plans. The underlying principle is identical: the plan can only claim reimbursement for costs it actually paid.

When medications are dispensed under a pharmacy lien, the MA plan never processes a pharmacy claim. The plan's subrogation demand — whether based on the MSP Act or the EOC's contractual provisions — cannot include costs the plan did not pay. The pharmacy lien amount is a separate obligation owed to a separate creditor.

This is particularly valuable in the MA context because MA plans manage pharmacy benefits through their Part D component. Every prescription filled through the MA plan's Part D benefit becomes a potential conditional payment that the plan will seek to recover. Medications on lien never enter the Part D claims system.

As Amar Lunagaria, PharmD, LienScripts' Chief Pharmacist explains, "MA plans are increasingly aggressive about recovering pharmacy costs because Part D benefits represent a significant portion of their total expenditures per member. Keeping medications on lien removes the highest-volume cost category from the plan's recovery demand."

Negotiation Strategies for MA Plan Demands

Strategy 1: Verify conditional payments with claims data. Request the plan's itemized conditional payment list. Compare it against the pharmacy lien dispensing records. Challenge any pharmacy line items for medications dispensed under the lien.

Strategy 2: Assert procurement costs. The MSP Act allows for a pro-rata reduction in the plan's recovery to account for attorney fees and litigation costs. Even MA plans using private contractual subrogation must account for the fact that the attorney's work produced the fund from which the plan recovers.

Strategy 3: Challenge the double damages threat. The MSP Act's double damages provision requires that the primary plan "failed to pay" when it had a responsibility to do so. In most PI cases, the tortfeasor's insurer paid the settlement — the question is reimbursement, not primary payment failure. The double damages threat is most potent against tortfeasor insurers who refuse to pay, not against attorneys disbursing settlement proceeds.

Strategy 4: Explore state insurance regulation. Some courts have held that MA plans are subject to state insurance regulation because they are licensed insurers, distinguishing them from self-funded ERISA plans. If the MA plan is subject to state law, anti-subrogation protections and the made-whole doctrine may apply.

[!TIP] Document everything in writing when negotiating with MA plan recovery units. MA plans have dedicated subrogation departments that handle hundreds of recovery files. Clear written communication reduces the risk of the plan escalating to litigation over a misunderstanding about the pharmacy lien's independence from plan-paid costs.

Timeline Differences: MA Plans vs Traditional Medicare

Traditional Medicare's conditional payment process follows a predictable timeline: reporting to BCRC, CPL issuance (60-90 days), dispute period, final demand after settlement. The process is slow but structured.

MA plans operate on a different timeline. They may assert their subrogation interest within days of learning about the PI claim. Many MA plans have automated systems that flag new claims and generate demand letters immediately. The recovery unit may contact the attorney before the case has progressed beyond initial treatment.

This early engagement is both a challenge and an opportunity. The challenge is managing the plan's expectations while the case is still developing. The opportunity is to establish early that medications are on lien and outside the plan's recovery scope, preventing the plan from including estimated pharmacy costs in its initial demand.
